Experience a spectacular day out in the crystal blue waters of the Gulf of Thailand in this guided day tour from Koh Samui. Your day starts with a light breakfast while on board a big boat departing from Nathon pier heading to Angthong National Marine Park. You will then transfer to a longtail boat or kayak to Mae Koh Island to see the Emerald Lake, fondly referred to by the locals as Talay Nai. To ensure you'll be full of energy for the rest of the day's activities, you'll enjoy a delicious Thai buffet lunch before kayaking at Wua Ta Lap Island or climbing to the Top View Point or hiking across a nature trail to the Lotus Cave. You'll also have enough time to swim or relax on the beach before boarding the boat back to Koh Samui.
